Objective To investigate the proportion , risk factors and tendency of change of stone composition in recurrent urolithiasis .Methods Eighty-five recurrent urolithiasis patients from 2002 to 2014 were enrolled in this retrospective cohort study .There were 61 male and 24 female patients with a median age of 51 (21-89) years at initial events.Among those patients, 70 had two events, 12 had three events, and 3 had more than 3 events.Compositions of initial and recurrent stones were measured by infrared spectrophotometry.Stone type, recurrence interval and recurrence frequency were studied as potential risk factors for composition change . Chi square test and logistic regression analysis were employed in the statistical analysis.Results Stone composition changed during recurrence in 26 patients ( 30.6%) . Univariate analysis showed the risk ratio of composition change in the patients with recurrence interval of 1-5 years was 0.518 (95%CI, 0.277-0.967, P<0.05) when compared with those of less than 1 year or more than 5 years.Logistic regression analysis showed the odds ratio of recurrence interval of 1-5 years was 0.231 (95%CI, 0.075-0.707, P=0.010).The mutual conversion between calcium oxalate and infection stones was mostly observed when stone composition changed during recurrence .Twenty percent of calcium oxalate stones changed to infection stones and 29.2% of infection stones changed to calcium oxalate .
Conclusions Stone composition changes in about one third patients of recurrent urolithiasis .The mutual conversion between calcium oxalate and infection stones is the most common change .Recurrence interval is an independent risk factor to predict composition change .Repeated stone analysis should be suggested to patients with recurrent interval of less than 1 year or more than 5 years.

AIM: To explore the role of extracellular signal-regulated kinases ERK1/2-STAT3 pathway in adaptive cytoprotection induced by H2O2 preconditioning in PC12 cells.METHODS: In PC12 cells,the experimental model of cytoprotection by H2O2 preconditioning against oxidative stress-induced injury was set up.The morphological changes in the apoptotic cells were observed by using of chromatin dye Hoechst 33258.The percent of apoptotic cells was determined by flow cytometry(FCM) with propidium iodide staining.The levels of p-ERK1/2 and p-STAT3 expression were detected by Western blotting assay.RESULTS: Preconditioning with H2O2 at concentration of 100 ?mol/L for 90 min obviously inhibited apoptosis induced by 300 ?mol/L H2O2,and both ERK1/2 and STAT3 were activated.UO126(10 ?mol/L,an inhibitor of ERK1/2) or AG-490(10?mol/L,an inhibitor of JAK2) significantly blocked the cytoprotection effect of H2O2 preconditioning.Moreover,UO126(10 ?mol/L) also markedly inhibited the up-regulation of p-STAT3 expression by H2O2 preconditioning.CONCLUSION: H2O2 preconditioning activates ERK1/2-STAT3 signal pathway,which may be one of the mechanisms underlying H2O2 preconditioning-induced cytoprotection.

Objective To investigate if distribution of stone composition and onset age in the upper urinary tract changed during the past 12 years in China.Methods There were 1 878 urolithiasis patients of the upper urinary tract in our hospital from 2003 to 2014 enrolled in present cross-sectional study.There were 1 300 male and 578 female patients with a median onset age of 46 (6-95) years.Stone composition was measured by infrared spectrophotometry.All the patients were divided into 3 groups according to the onset year:Year 2003-2006,Year 2007-2010 and Year 2011-2014.The distributions of stone types were compared among the 3 groups.Age and gender were included as potential confounders.Chi square test,P trend test,Kruskal-Wallis test and logistic regression were employed in the statistical analysis.Results Calcium oxalate was the most common type with a dominant proportion of 78.1％ (1 466/1 878),while uric acid had a small proportion of 4.8％ (91/1 878).The proportions of uric acid in the 3 groups were 2.7％ (12/441),5.1％ (39/758) and 5.9％ (40/679),showing an increasing trend (P ＜0.05).Multivariate analysis showed that year group was independently correlated with the proportion of uric acid,with an OR of 1.385 (95％ CI,1.027-1.867).From 2003 to 2014,the proportion of uric acid calculus increased by 0.42％ (95％ CI,0.25％-0.59％) annually.The median ages of disease onset were 43,46 and 49 years respectively in those three groups,also showing an increasing trend with time (P ＜0.01).Conclusion From 2003 to 2014,the proportion of uric acid and onset age in patients of upper urinary tract calculi were increased in the present cohort.

Objective: To investigate the causal relationship between antioxidant nutrients and pregnancy complications, so as to provide the reference for the prevention and treatment of pregnancy complications. Methods: Data of seven antioxidant nutrients including vitamin A, vitamin C, vitamin E, selenium, zinc, copper and iron were collected from genome-wide association study (GWAS) Catalog database, and data of four pregnancy complications including gestational diabetes mellitus, pre-eclampsia, spontaneous abortion and preterm birth were collected from the Finland database. Single nucleotide polymorphism (SNP) data were collected, and 27 SNPS strongly correlated with seven antioxidant nutrients were selected as instrumental variables. Mendelian randomization (MR) analyses were performed using the inverse-variance weighted (IVW) method with seven antioxidant nutrients as exposures factors and four pregnancy complications as outcome variables. The heterogeneity was assessed using the Cochran's Q test, the horizontal pleiotropy was assessed using the MR-PRESSO test and MR-Egger regression, and the robustness of the results was verified with the leave-one-out. Results: Cochran's Q test showed heterogeneity of MR results between vitamin C and gestational diabetes mellitus, preeclampsia and preterm birth, between vitamin E and iron and gestational diabetes (all P<0.05), and a random effect model was employed. There was no heterogeneity in other results (all P>0.05), and a fixed effect model was employed. MR analysis results showed that there was no causal association between seven antioxidant nutrients and the risk of four pregnancy complications (all P>0.05). MR-PRESSO test and the MR-Egger regression identified no horizontal pleiotropy of instrumental variables (both P>0.05). Conclusion This study did not find genetically predicted associations of antioxidant nutrients with pregnancy complications.

Directive 2004/24/EC of the European Parliament and the Council entered into force on April 30th, 2004. After 7 years, there is no Chinese medicine to be registered successfully in European market as traditional herbal medicinal products. The thesis gives some ideas to tackle this problem. Procedure for the Preparation of Community Monographs for Traditional Herbal Medicinal Products (EMEA/HMPC/182320/2005) published by European Medicines Agency is an important guidance for traditional herbal products to enter European Community monographs. The thesis introduces and details the procedure as well as gives feasible suggestions about the procedure. It suggests that Chinese medicines enter European Community monographs first, and then apply the registration according to the directive 2004/24/EC. This is an easier access to European market.
